Bought the IBUKI + as a bedroom air purifier. The size and noise level are perfect. I downloaded the app, which allows me to monitor and adjust the unit from my iPhone.
I suffer from cat dander allergies and within a few days of running this in my main area of my house where the cat is most the time I have not been nearly as stuffy and itchy. I think it’s working great.
I bought 4 of these to take care of my entire house (3500sq ft) & so far so good. They are very quiet and I like how I can program them from my phone. I also like how a glance at them tells me if my filter is getting dirty.
